Hello everyone welcomes your Thursday afternoon news have I'm tiny Rivera oh and for Sara Murray ... Iraq Prime Minister Hider al Mahdi tells reporters Thursday Iraqi intelligence uncovered a plot ... to attack Paris and New York Mets resistance ... and he says he shared the information with U S intelligence ... so what are investigators doing to assess this the rap for answers were joined by Christopher boss managing director ... at Insite Security and a twenty four year veteran ... of the FBI crisper thank so much for being with us ... certainly ... and first up very simply what do you make of this the rats do you think it's credible ... well credibility in Amman are two different issues now to talk about the fact that to ... the bill even got this from foreign fighters in Iraq ... so we haven't identified where they're from and where they may have a previous network ... aam they can very easily be some credibility to the planning on desiring ... of targeting these ... subway systems use transit systems in Paris and New York ... because they've always desired to target these college planning is in process ... and sketching when David first out of Iraq and re rating in Iraq ... is actually is unlikely that its eminent power that doesn't mean ... that they have discovered something that indicates that there has been some planning so those are ... two definitions ... EU made the point that is unusual that this is been picked up only by the Rockies without some branch of the US government also knowing about it but isn't that possible we don't always know what the US government now owns ... in all courses possible and everyone within the United States government ... is treating them as such right now ... they haven't raised on their alarm bells you know they have gone to death on five over this more than likely ... that the same time ... they're realizing this could be a threat that they didn't know about the Foreign The taking a hard look at everything he ... didn't want to get the information script is possible in assessing so ... it wouldn't take very seriously ... are didn't feel right now the attack is imminent probably not that they're not willing to take the chance to look at the very heart ... if the ISS capable pulling off a quart meeting international attack of the week to understand it to be is a regional threat to more than an international fact at this point ... already clearly ISIS's problems are all regional ... the Arab governments and in the region on now for him or the United States ... and ISIS has a military problem ... on the turf that they've taken care of said their biggest problems are regional ... they've been engaged in recruiting worldwide ... and their fighters coming from all over the world for them ... said somewhat of a network ... that that the network to drain resources in their direction ... and that morning their military assets in other directions into bigger problems than our own home turf right now and Chris for living in your into squares and growth and how it hasn't I saw Kai tak ... and that potentially in that group is more threatening to the US ... you think something like this is more likely to come out of squares that ... that's really hard to say right now and then a lot of it has to do with how comfortable they are and where their headquarters or so to speak ... the Arcata was able to mount threats ... on American soil when they were comparably hiding relatively speaking comparably hiding in Afghanistan because they were being protected by the Taliban ... this sort of a safe haven if you well ... ICE's in these other groups don't have quite the same safe haven the ... arcade at that time would Stephen looker of planning ... attacks in other countries ... I think you so much for that insight Christopher boss ... thank you read me on ... well the right back with more news have been thirty seconds away ... an outside ... the markets ... two ... stocks fell sharply in Treasury bonds rallied as investors piled into asset seen as say amid stepped up worries over global economic growth ... the Dow closed at sixty nine hundred and forty six the Nasdaq closed at four thousand four hundred and sixty seven and the Essen P ... close to one thousand nine hundred and sixty six ...

I've known and lesser holders held the position of Attorney General since ... two thousand and nine he was ... most recently in the headlines for heading down to Ferguson Missouri to help ease tensions there between ... the community and police in the wake of a black teenagers back what will Mr Holder's larger legacy be ... close to a few things one is going to be ... you know these these fears today's them gone on around terrorism because that's really how this time started ... he wanted ... to try the nine eleven suspects ... in New York ... Commerce in your basically stopped him from doing that you want to close Guantanamo Bay ... Congress stop him from doing that so that's one part of the legacy ... the other part is given the areas of the vehicle writes that he fought on gay rights civil rights voting rights ... I'm dozer those are part of his legacy Inose or what he's the most focused on lately ... yet apart his legacy is obviously Wall Street investigations ... he's been criticized for not putting any senior executives in jail for ... the ... meltdown in two thousand ate ... but he's also got massive new multi billion dollar settlements from a lot of the big banks and that's a big part is lazy to ... write so looking at what names are coming up that's possible replacement ... for the two became king they come up right away our Kapur draw blur she's the former White House counsel ... very close to the president his senior staff ... so they have comfort level with her ... but because he's so close to the president his senior staff there could be some complications their among Senate Republicans ... another is gonna really is the solicitor general ... he argued in defense of Obamacare before the Supreme Court and essentially won that argument when all was said and done ... so those that change that fraud is also Manhattan U S Attorney Preet Ferrara ...
